Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer wall plate mounting structure for mounting a ceramic outer wall plate with screws or nails.

[0002]

2. Description of the Related Art In recent years, a ceramic-type outer wall plate having a highly designed rugged pattern is often used. As a construction method for attaching the outer wall plate to the wall surface base material, there are metal fitting construction and screw (or nail) fastening construction. The former metal fitting construction is a construction method in which the real edge portion of the outer wall plate is fitted and held by the fastening metal fitting fixed to the wall surface base material with screws or nails. Since gaps are allowed, displacement of the building frame due to earthquake and wind pressure load,
Displacement displacement of the outer wall plate is allowed according to expansion and contraction of the outer wall plate due to temperature changes and repeated absorption / drying of rainwater, thereby relaxing the stress applied to the fastening part of the outer wall plate and preventing cracks in the outer wall plate. To be done.

[0003] However, the metal fittings are required to have the strength of the actual edge portion of the outer wall plate, and the thickness of the ceramic outer wall plate is 15 mm.
Otherwise, the strength of the real part is insufficient, and there is a drawback that the real part of the edge of the outer wall plate is easily cracked by wind pressure load or seismic load. Therefore, a thick outer wall plate must be used, and the cost of the outer wall plate to be used increases accordingly, resulting in a high construction cost. Moreover, a special fastening metal fitting is required, which also contributes to the high construction cost.

On the other hand, in the screw (or nail) fastening, as shown in FIG. 9, the outer wall plate 1 is attached to the wall surface base material 11 such as C-shaped steel.
It is a construction method in which 2 is applied and fixed to the wall surface base material 11 with screws 13 or the like from above. This construction method does not require a special fastening bracket, can be easily installed using extremely inexpensive screws 13 and the like, and even with a relatively thin outer wall plate, the mounting strength is large, so a relatively thin outer wall plate can be used. As a whole, there is an advantage that the construction cost can be reduced.

[0005]

However, unlike the metal fitting construction described above, the screw (or nail) fastening construction is different from the outer wall plate 1 as described above.
Since 2 is closely fixed to the wall surface base material 11 with screws 13 or the like, the relative displacement of the outer wall plate 12 with respect to the wall surface base material 11 is hardly permitted. As a result, the displacement of the building frame due to earthquakes and wind pressure loads, changes in temperature, and absorption of rainwater
With respect to expansion and contraction of the outer wall plate 12 due to repeated drying, excessive stress may concentrate on the fastening portion of the screw 13 of the outer wall plate 12 and the outer wall plate 12 may be cracked. In particular, when the wall surface base material 11 is a steel frame, the wall surface base material 11 is almost rigid, and the cushioning / deformability of the base material itself such as a wall surface base material made of wood can hardly be expected.
The stress concentrated on the fastening portion 2 becomes extremely large, and the outer wall plate 12 is more easily cracked.

The present invention has been made in view of the above circumstances, and therefore an object thereof is to alleviate the stress applied to the fastening portion of the outer wall plate while performing the screw (or nail) fastening construction. Another object of the present invention is to provide an outer wall plate mounting structure capable of preventing cracks in the outer wall plate.

[0007]

In order to achieve the above object, the outer wall board mounting structure according to claim 1 of the present invention has a ceramic base outer wall board as a screw or a nail (hereinafter referred to as "screw or the like") as a wall base material. Is attached from the front surface side of the outer wall plate, and a spacer member having a certain thickness is sandwiched between the outer wall plate and the wall surface base material, and the spacer member is formed into a shape extending in the vertical direction. By mounting the screws through the large holes or recesses that are formed, the screws or the like can be freely tilted by the holes or recesses around the screws or the like in accordance with the relative displacement of the outer wall plate with respect to the wall surface base material. Constructed so that there is a gap that can be made, and further, the wall

It is a thing. Here, the thickness of the spacer member is 3 to 15 m.
It is preferable to set m, and it is preferable that the hole or the recess of the spacer member has a lateral width of 2 to 5 times the diameter of a screw or the like. The large holes or recesses of the spacer member having such a thickness allow a gap to be formed in the peripheral portion of the screw or the like between the outer wall plate and the wall surface base material, so that the screw or the like can be freely tilted in the gap. Allows the relative displacement of the outer wall plate with respect to the wall base material,
The stress concentration on the fastening part of the outer wall plate is mitigated and the outer wall plate is prevented from cracking.

Moreover, by simply sandwiching the spacer member between the outer wall plate and the wall surface base material, it is possible to easily and surely form a gap in the peripheral portion of the screw or the like. Further, the size of the void can be easily adjusted by the thickness of the spacer member and the size of the hole or recess. Furthermore, the holes or recesses of the scan pacer member

In this case, as in claim 2 , the spacer member may be formed of any of wood, wood plywood, plastic plate, and narrow wall material such as outer wall plate. These materials are
Both of them have the same or higher cushioning properties and deformability as the outer wall plate, and this cushioning property and deformability can also alleviate the stress concentration on the fastening portion of the outer wall plate. Moreover, it is possible to recycle the narrow width material, which is no longer needed after being cut from the outer wall board, wood, wood plywood, etc., as a spacer member.

Further, as in claim 3, a double-sided adhesive tape may be attached in advance to the back surface of the spacer member. By doing so, it is possible to attach the spacer member to the wall surface base material side by an extremely simple construction method of attaching the spacer member at the time of construction.

BEST MODE FOR CARRYING OUT THE INVENTION A first embodiment of the present invention will be described below with reference to FIGS. First, FIG. 2 and FIG.
The base assembly structure for attaching the ceramic outer wall plate 21 will be described based on FIG. A base 23 made of square steel is fixed on the foundation concrete 22 via anchor bolts 24. On the base 23, a wall surface base material 25 made of C-shaped steel is erected vertically by welding or bolting via L-shaped steel 26. A strip-shaped spacer member 27 is attached to the front surface of each wall surface base material 25 with a double-sided adhesive tape 28 (see FIGS. 3 and 4) which is attached to the back surface of the spacer member 27 in advance. The double-sided adhesive tape 28 may be attached to almost the entire length of the spacer member 27. However, the double-sided adhesive tape 28 only needs to be able to temporarily fix the spacer member 27 until the outer wall plate 21 is screwed. As shown, the spacer member 27
It suffices to partially attach the plurality of points with the double-sided adhesive tape 28.

In this case, the spacer member 27 is made of wood, wood plywood, plastic plate, or narrow width material such as outer wall plate, and a large number of elongated holes 29 are formed along the center line thereof. Since the spacer member 27 is attached to the wall surface base material 25, the width of the spacer member 27 is narrower than the width of the wall surface base material 25 (for example, 50 to 100 mm).
Is appropriate. Further, the thickness of the spacer member 27 is preferably 3 to 15 mm in order to secure a void having a sufficient thickness in the peripheral portion of the screw 30 as described later. Further, the lateral width of the elongated hole 29 formed in the central portion of the spacer member 27 is 2 to 5 times the diameter of the screw 30 (for example, in order to secure a void of a sufficient width in the peripheral portion of the screw 30 as described later). The size is preferably 10 to 25 mm.

As shown in FIG. 2, the waterproof sheet 3 is provided on the front surface side of the spacer member 27 attached to each wall surface base material 25.
1 is attached, and the outer wall plate 21 is attached from above and fixed to the wall surface base material 25 with screws 30. Outer wall plate 2
As shown in FIG. 1, each screw 30 for fixing 1 is fastened to the wall surface base material 25 through the long hole 29 of the spacer member 27.

According to the mounting structure of the outer wall plate 21 constructed as described above, as shown in FIG. 1, the elongated hole 29 of the spacer member 27 sandwiched between the outer wall plate 21 and the wall surface base material 25 is provided. In addition, since the construction is performed through the screw 30 for fixing the outer wall plate 21, the screw 30 is provided between the outer wall plate 21 and the wall surface base material 25 by the long hole 29 of the spacer member 27.
There will be voids around the area. In this structure,
When the outer wall plate 12 is displaced and displaced due to the displacement of the building body due to an earthquake or wind load and the expansion and contraction of the outer wall plate 12 due to repeated temperature changes and repeated absorption and drying of rainwater, FIG.
As shown in (b), the screw 30 tilts in the direction in which the outer wall plate 21 is displaced.

On the other hand, in the conventional structure shown in FIG. 9, there is no space between the outer wall plate 12 and the wall surface base material 11 for allowing the tilting of the screw 13, so that the outer wall plate 21 tends to be displaced. However, the screw 13 could hardly be tilted, and the relative displacement of the outer wall plate 12 with respect to the wall surface base material 11 was hardly allowed. For this reason,
During an earthquake or when the outer wall plate 12 expands or contracts, excessive stress may concentrate on the fastening portions of the outer wall plate 12 and the outer wall plate 12 may crack.

In this respect, in the above embodiment, the long hole 2 of the spacer member 27 is provided between the outer wall plate 21 and the wall surface base material 25.
Since a gap is formed in the peripheral portion of the screw 30 by the screw 9, the screw 30 can freely tilt in the gap, thereby allowing the relative displacement displacement of the outer wall plate 21 with respect to the wall surface base material 25. . Thereby, the stress concentration on the fastening portion of the outer wall plate 21 can be relieved, and the outer wall plate 22 can be prevented from cracking. Moreover, since it is a screw fastening, a dedicated fastening fitting is not required, it can be easily installed using the extremely inexpensive screw 30, and the relatively thin outer wall plate 21 has a large mounting strength, so that the outer wall is relatively thin. Since the plate 21 can be used, there is also an advantage that the construction cost can be reduced as a whole.

Further, in the above embodiment, the spacer member 2
7 is made of wood, wood plywood, plastic plate, or narrow material such as outer wall plate, so the spacer member 27
Can have a buffering property / deformability equal to or higher than that of the outer wall plate 21, and this buffering property / deformability also has an effect of relieving the stress concentration on the fastening portion of the outer wall plate 21. In combination with the displacement allowance effect of the gap, the outer wall plate 12 can be more reliably prevented from cracking.
Moreover, the small width material that is no longer needed after being cut from the outer wall plate, wood, wood plywood or the like can be recycled as the spacer member 27, which leads to resource saving and the spacer member 27 can be manufactured at an extremely low cost.

Further, in the above embodiment, the spacer member 2
Since the double-sided adhesive tape 28 is previously attached to the back surface of 7, the spacer member 27 can be attached to the wall surface base material 25 side by an extremely simple construction method of attaching at the time of construction, and construction can be performed extremely efficiently. .

In the first embodiment described above, the waterproof sheet 31 is provided so as to overlap the back surface of the outer wall plate 21, but in the second embodiment shown in FIGS. 5 and 6, the wall surface base material 25 is used. The waterproof sheet 31 is attached to the surface of the spacer member 27, and the spacer member 27 is attached to the waterproof sheet 31 with a double-sided adhesive tape.
The outer wall plate 21 is attached to the wall surface base material 25 with screws 30. Thereby, a ventilation layer corresponding to the thickness of the spacer member 27 can be formed between the back surface of the outer wall plate 21 and the waterproof sheet 31, and the air flowing through the ventilation layer allows the moisture on the back surface side of the outer wall plate 21 to move to the outside. It can be discharged, and dew condensation on the back surface of the outer wall plate 21 can be prevented, and the durability of the outer wall plate 21 can be improved.

In both the first and second embodiments described above, the elongated hole 29 (through hole) is formed in the spacer member 27, but in the spacer member 27 as in the third embodiment shown in FIG. A recess 32 having substantially the same size as the elongated hole 29 may be formed, and a screw 30 may pass through the recess 32 to form a void in the peripheral portion of the screw 30 in the recess 32. In this configuration, the screw 30 can freely tilt in the recess 32, so that the outer wall plate 2 with respect to the wall surface base material 25 can be tilted as in the first and second embodiments described above.
The relative displacement of No. 1 can be allowed by the gap in the recess 32, and the stress concentration on the fastening portion of the outer wall plate 21 can be relieved.

It should be noted that the shape of the hole 29 or the recess 32 for forming a gap in the peripheral portion of the screw 30 is not limited to the long hole or the long groove,
Other shapes such as circular holes and circular recesses may be used.
The shape is not limited as long as it is a hole (or a recess) having a size 2 to 5 times the diameter of the screw 30 for fixing the outer wall plate 21.

In each of the above embodiments, the spacer member 27 is used to open the gap around the screw 30, but the fourth to seventh portions shown in FIGS. As in each of the above embodiments, the surface of the wall surface base material 35-38 is formed in a concave shape, the outer wall plate 21 is directed to the front surface side of the wall surface base material 35-38, and the screw 30 is provided on the outer wall plate 21. By fixing to the concave portions 39 to 42 of the materials 35 to 38, the concave portions 39 to 42 of the wall surface base materials 35 to 38 may form voids in the peripheral portion of the screw 30.

In this case, the fourth portion shown in FIGS.
In the fifth and fifth embodiments, square pipe columns made of steel are used as the wall surface base materials 35 and 36, and in the sixth and seventh embodiments shown in FIGS. 8C and 8D, the wall surface base material 37, C type steel is used as 38. In addition, in FIGS. 8A and 8C, the concave portions 39 and 41 are formed in a shape curved in an arc surface over the entire length of the wall surface base material 25, and in FIGS.
In (d), the concave portions 40 and 42 are formed in a V-groove shape over the entire length of the wall surface base material 25. In any of these embodiments, the concave portions 39- of the wall surface base materials 35-38
The screw 30 can freely tilt in the void formed by 42, thereby allowing relative displacement of the outer wall plate 21 with respect to the wall surface base materials 35 to 38, and stress concentration on the fastening portion of the outer wall plate 21. Therefore, the outer wall plate 21 can be prevented from cracking. Moreover, since a spacer member is not required as a means for forming a void in the peripheral portion of the screw 30, workability and cost performance can be further improved.

Also in each of the embodiments shown in FIG. 8, a waterproof sheet may be sandwiched between the outer wall plate 21 and the wall surface base material 25.

In each of the embodiments described above, the wall surface base materials 25, 35 to 38 are made of steel frame, but may be made of wood. When the present invention is applied to the wall surface base material of wood, nails may be used instead of the screws as a means for fixing the outer wall plate.

[0028]

As is apparent from the above description, according to the outer wall plate mounting structure of claim 1 of the present invention, a spacer member having a thickness of 3 to 15 mm is provided between the outer wall plate and the wall surface base material. A shape that is sandwiched and extends vertically in the spacer member
A space formed by inserting a screw or the like into a hole or recess whose lateral width is 2 to 5 times the diameter of the screw or the like, and allowing the screw or the like to tilt around the screw or the like by the hole or recess. Since the outer wall plate is opened, the relative displacement of the outer wall plate with respect to the wall surface base material can be allowed, the stress concentration on the fastening portion of the outer wall plate can be relaxed, and the outer wall plate can be prevented from cracking. it can. Moreover, there is no need for a special fastening metal fitting, it can be easily installed using extremely inexpensive screws and nails, and since the mounting strength is large even with a relatively thin outer wall plate, a relatively thin outer wall plate can be used, in general, Construction costs can be reduced.

Further, by simply sandwiching a spacer member having a large hole or a concave portion between the outer wall plate and the wall surface base material, it is possible to easily and surely form a void in the peripheral portion of the screw or the like, which leads to improvement in workability. . Moreover, a hole or recess of the scan pacer members, since the form a long shape extending in the vertical direction, it is possible to increase also the gap of the peripheral portion in the vertical direction, such as screws, can be further improved workability it can. In addition, a waterproof seal should be placed between the wall base material and the spacer member.

A ventilation layer corresponding to the thickness of the pacer member is formed.
Therefore, the ventilation layer prevents condensation on the back of the outer wall board.
Therefore, the durability of the outer wall plate can be improved.

Further, in claim 2, the spacer member, wood, wood plywood, plastic plate, so formed by any of the narrow material of the outer wall plate, wall panels equal to or more cushioning-deformed spacer member Can have sex,
This cushioning property and deformability can also provide an effect of relieving the stress concentration on the fastening portion of the outer wall plate. Moreover, the small width material that is no longer needed after being cut from the outer wall plate, wood, wood plywood, etc. can be recycled as the spacer member, and the demands for resource saving and cost reduction of the spacer member can be satisfied.

Further, in claim 3 , since the double-sided adhesive tape is adhered to the back surface of the spacer member in advance, the spacer member is attached to the wall surface base material side by an extremely simple applying method when applying the spacer member. It is possible to improve the workability.
